2D Dual Phased Arrayfor Angle Beam Inspection of Coarse Grain Materialswith Replaceable Wedge

What is a Phased Array Probe?

•  Variable beam size or aperture

•  Variable refracted angle

•  Variable roof angle and focus

•  Low noise wedge design

•  Standard Hypertronics connector

Key Features 

Advantages of 2D Dual Angle Beam Phased Array•  Dual, transmit/receive design improves signal to noise

ratio in coarse grain materials.

•  4 x 7 element matrix on both transmit and receive sidesenables variable refracted angle and variable “roofangle” to control effective focal depth.

•  Used as transmit/receive pair for dual operation.

•  Each half can also be used as single array probe inpulse-echo mode.

•  Eliminate multiple inspections with fixed angle probes.

•  Increase sensitivity and signal to noise ratio with elec-tronic focusing.

•  Inspect hard to access areas from a single contact point.

•  High sensitivity, broadband piezocomposite elements

•  Reduce mechanical and manual manipulation.

•  Replaceable wedges maximize service life of the array probe.

A phased array probe can be compared to a large singleelement transducer whose active area has been sub-divided into small segments or elements. When connectedto appropriate instrumentation, the beam from the phased

array is steered and focused electronically by sequentiallyfiring the elements of the array. Angle and focal depth aregenerated electronically by the instrumentation and canbe changed on each pulse repetition.
